First, I'll send you to the waiting room, a safe space we created. While there, speak with the *Keeper of the Gap*. He'll allow you to enter the dimension gap.

However, they are classified based on the place that they manage.

*Level 30's are managed by Recruits, Level 40's by Privates, Level 50's by Officers, Level 60's by Captains, Level 70's by Commanders, and the higher levels by Heroes*.  Don't forget this, and visit a keeper of the gap appropriate for your level. Well, good luck to you.
